title: Effect of prior hepatitis B infection on serum IgE levels in patients with human immunodeficiency virus infection.
abstract: BACKGROUND
  Advanced HIV infection is associated with increased serum IgE levels, which in turn have been associated with a poor prognosis. Our preliminary data revealed that serum IgE levels were significantly elevated in HIV seropositive injection drug users compared with HIV seropositive non-injection drug users. Since viral hepatitis is common among injection drug users and is itself associated with elevated serum IgE levels, we studied whether there was an association between increased serum IgE levels and positive hepatitis serology in HIV-seropositive patients.
  
  
  METHODS
  A retrospective cross-sectional analysis was performed. The medical records of ambulatory HIV-infected patients in an ongoing study were reviewed. Forty-five patients had hepatitis A, B, and C serology performed. The associations between serum IgE levels and hepatitis A, B and C antibodies, CD4 and CD8 lymphocyte percentages, injection drug use, and sex were analyzed by univariate and multiple regression analyses.
  
  
  RESULTS
  On univariate analyses, hepatitis B antibody was significantly associated with increased serum IgE levels in HIV-infected subjects (P = .013), especially in those with AIDS (P = .015). Multiple regression analyses controlling for CD4 lymphocyte percentages, sex, and drug use, confirmed that hepatitis B antibody status remained significantly associated with increased serum IgE levels (P = .05). There was no association of serum IgE levels with hepatitis A or C serology.
  
  
  CONCLUSIONS
  Prior hepatitis B infection is significantly associated with increased serum IgE levels in advanced HIV infection. The clinical implications of this finding deserve further study.
